This paper is devoted to the study of thermodynamic properties on the Berthelot fluid. The Helmholtz
free energy，entropy，Gibbs function，internal energy and enthalpy of monoatomic Berthelot fluid are derived;the
parametric solutions of the Berthelot fluid two coexisting phases are obtained，and phase diagrams，thermodynamic
behaviors near the critical point and associated properties are discussed by using the parametric solutions. The study
provides analytic theory of thermodynamics and phase transition for substances satisfying the Berthelot fluid.
